Cosine functions are positive in quadrant 4
Here is a helpful mnemonic All Students Take Calculus (might be helpful in the future)
Answer:

Step-by-step explanation:
The given function is
![y=\sqrt[3]{x+8}](https://tex.z-dn.net/?f=y%3D%5Csqrt%5B3%5D%7Bx%2B8%7D)
The range refers to the values of y for which x is defined.
We solve for x to obtain;


This is a polynomial function in y.
x is defined for all values of y.
Therefore the range is all real numbers.
or

The first choice is correct.
Answer:
A
Step-by-step explanation:
A= r(pi)^2
A= 9 pi ^2

Answer:
x=27, y=18
Step-by-step explanation:
Angle CB is 128, which means angle AC is 72. We can confirm angle O is also 72, since the lines are straight. Angle AM is 27, because AN is a right angle. 63+72+27= 162 180-162=18 Angle ND is 18.
